EDlVIN L. LLOYD, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE JOLY STOPPER COMPANY, OF SAME PLACE.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 395,910, dated January 8, 1889. Application filed June 25, 1838. Serial No. 278,127. (No model.)

To all whom, it may concern.-

Be it known that I, EDWIN L. LLOYD, a citizen ot' the United States, and a resident of Philadeh'ihia, Pennsylvania, have invented certain Improvements in Bottle-Stoppers, of which the following is a specification.

My invention relates, mainly, to that class of bottle-stoppers in which the sealing is effected by means of a flexible disk jammed against the walls of the bottleneck, one object of my invention being to prevent the accidental displacement or loosening of a stopper of this character, a further object being to eheapen the construction of the stopper, and a still further object being to provide for the ready insertion of the stopper, the ready forcing of the same into the bottle to open the same, and the ready removal of the stopper from the bottle.

In the accompanying drawings, Figure 1 is a sectional view of part of a bottle with my improved stopper applied thereto. Fig. 2 is a similar viewsllowing the mode of removing the stopper from the bottle. Fig. 3 is a perspective view of the parts ol. the stopper detached [from each other, and Figs. 4 and 5 are views illustratingmodified forms of the stopper.

As before remarked, my invention is directed mainly to that cl ass of stoppers in which a flexible diskpreferably of rubberis jammed in the neck of the bottle to close or seal the same, and one feature of my invention consists in combining with a stopper of this character a locking device to engage with the flaring inner portion of the neck and prevent the accidental outward loosening or dislodginent of the stopper from the neck, the locking device, however, not interfering with the ready forcing of the stopper into the bottle in the opening of the same, or with the ready removal of the stopper from the bottle in the proper way.

As shown in Fig. l, the stopper-consists of a tubular shank, a, having at the upper end a sealing disk, 1), and at the lower end a locking-disk, d, the latter being of slightly greater diameter than the sealing-disk, and the whole being confined to a central rod or stem, f, by washers g and 7b, the latter being interposed between the lower or looking disk,

(I, and an eye, m,at the inner end of the stem f, while the washer g is interposed between disk, I), which projects beyond the washer 71. is

bent upward and jammed firmly against the walls of the bottle-neck, while the lower disk, (7-, occupies such a position in the .flaringlower portion of the-neck ot' the bottle that it is free to expand to its full extentand bears against said flaring walls of the neck, as shown. The lower washer, 71, is of such diameter that the stopper cannot be withdrawn from the neck while occupying the position shown in Fig. 1, as the projecting rim of the disk (I will be jammed by the washer against the sides of the neck, and will thus serve as a lock to prevent upward movement of the stopper.

In opening the bottle the stopper is driven down into the same, and in order to remove the stopper its position is reversed, a suitable implement engaging with the eye on of the stopper and drawing the latter in its inverted position from the neck, as shown in Fig. 2, both flanges b and d being free to yield when the stopper is drawn in this direction, so that they afford no obstacle to the free removal of the stopper from the bottle. The latter can then be cleaned in any of. the usual bottlewashing machines, and the stopper can also be readily cleaned prior to reinsertion in a bottle.

\Vhile I prefer to form the stopper in the manner shown in 3, this construction is not absolutely necessary. For instance, the disks b and (Z may be separate from each Ohl161,bl16 tubular shank a being dispensed with and washers g h being used in place of the same, that portion of the stem f between these washers being flattened, as at a, to form shoulders, which hold the washers in place. (See Fig. 4.) A substitute may also be used for the inner disk, (Z, if desired. For instance, in Fig. 5 I have shown the inner end of the stem (0 bent so as to form a 1oop,-d, the free end of which has a little play, so that in pers shown the rigid st e111 f projeets some distanee above the upper washer, 9, thus not 1 only providing a ready means of applying the stopper to the plunger of the bottle-filling machine, but also li'ac'ilitating the pushing ol' 1 the disk, said steln alsohaving bGiOWtht lockthe stopper into the hottlo in order to open the same.

The lower disk, (I, in tho stoppers (shown in l igs. i and 4) serves as a gas-stop when the stopper n1a v he withdrawn when inverted, all

bottle contains ellervosoont liquids; hut in the stoppers thero shown this latter function is incidental to tho main function ol the disk, which is that of a look. to provont dispiaoon 1ont oi the upper or sealing disk 'l'rofn its proper position in tho nook ot' the hot tlo.

l-iaving thus dosorihed my invention, what I oiailn, and dosiro to soonro Irv Letters Patent,

l. The ooinhination, in a hottlo-stoppor, oi

gagemont with the tapering noek after the stopper is insortoi'l, and heyond said look a portion tfor ongagi 11 g with an oXtraotor, whorehy the stopper may ho withdrawn when invorted, all sul'1st antially as speeiiiod.

2. The combination, in a bottle-stopper, of a stem having an upper tie'xihle disk and a washer of slightly s111aller diameter than the disk, and having helow said sealing-disk an other flexible disk free to yield 011 the inward movement of the stopper, a washer against which the disk bears to prevent. yield in the other di rootion, and beyond said washer a portion for engaging with an extractor, whereby the stopper 111a v ho withdrawn when invertt-a'l, all substantially as spoeiiiml.

I The combination, in a hottle-stopper, ot' a tubular shank, hflYill a sealing-disk at the upper end and a loekingdisk at: the lower end, with a stem p2 sing through said tnbnlar shank and having ahovo the sealing-disk a washer of slightly smaller diameter than ing-disk a washer serving as a hae'king for said disk, and beyond said washer a portion tor engaging with an extractor, whereljrv the sn'hstautiallv as speoiliet'l.

-i-. The within-desoril1ed sealing dovioo tor a hottio-stoppor, the same oonsisting of a tubular shank with disks at top and ljiottonn the whole being of ruhher or equivalent flexi- 1 hlo 111atorial, all suhstiantiallv as speoitied.

'lho ooinhination oi tho sealing portion ot the stopper, r-oniprising a tubular shank having a sealing-disk at the top and a loek ii'lg-disk at the hottom, oonti11ing-washors at i the opposite ends oi said shank, and a central ston1 having an oye at the innor end hearing against the lower washer, and a thtttened portion torniing shou'h'lors tor retaining tho upper washor, all snhstant iall v as specified.

In test i mony whereof ihave gnedn'iy name to this SIlQCii'iOili'iUll in the prosonoo of t wo snhsorihing witnossos.
